"Okay. Let me out. This is not funny." Sam yells as we talk to him through the little barred window in the door. "Damn straight." Dean growls. "Dean, come on. This is crazy." Sam exclaims. "No. Not until you dry out." Dean said. "Look, I'm sorry. I shouldn't have lied to you and to (y/n). Just open the door." Sam said and I wrap my arms around myself. "You don't have to apologize. It's not your fault. It's not your fault that you lied to us over and over again. I get it now. You couldn't help it." Dean said. 

"I'm not some junkie." Sam yells. "Really? I guess I've just imagined how strung out you've been lately." Dean accused. "You're actually trying to twist this into some kind of ridiculous drug intervention?" Sam asked, angrily. "If it smells like a duck." Dean said, shrugging.  "Dean, I'm not drinking the demon blood for kicks. I'm getting strong enough to kill Lilith." Sam said and I raise an intrigued eyebrow at this.

"Strong?" Dean asked.

"Yeah." Sam said.

"This is about as far away from strong as you can get. Try weak. Try desperate. Pathetic." Dean spat. "Killing Lilith is what matters. Or are you so busy being self-righteous you forgot about her?" Sam growls. "Oh, Lilith's gonna die. Bobby, (y/n) and I will kill her. But not with you." Dean informs. "You're not serious." Sam said, disbelieving. "Congrats, Sammy. You just bought yourself a benchwarmer seat to the apocalypse." Dean said.

"Dean, look—no, wait—" Sam said, quickly, but Dean shuts the window cover. "Come back here. Dean! Let me out of here! Dean! Let me out of here! Let me out! Dean!" Sam shouts as Dean walks away. I sigh and look over at the door for a few moments before I turn away from it while Sam continues to shout.

Bobby pours three glasses of whiskey and hands one to Dean then the other to me. "Stop! Stop!" We hear Sam shout and I frown and look down at the glass of whiskey. "How long is this gonna go on?" Dean asked Bobby. "Here, let me look it up in my demon-detox manual. Oh wait. No one ever wrote one. No telling how long it'll take. Hell, or if Sam will even live through it." Bobby said then the phone rings.

Bobby sighs and answers. "Hello." he answers then his face turns to annoyance and anger. "...Suck dirt and die, Rufus. You call me again, I'll kill you." he yells and hangs up. "What's up with Rufus?" I asked Bobby, curiously. "He knows." Bobby said then the phone rings again and he answers it. "I'm busy, you son of a bitch. This better be important." he said then his face turns to shock and fear.

"The news. The news ain't good." Bobby said as I had my laptop open and looking through some news stories. "This is what Rufus called about? Key West sees ten species go extinct." I said, pointing at the article on screen. "Yep. Plus Alaska. Fifteen-man fishing crew all stricken blind, cause unknown. New York, teacher goes postal, locks the door, kills exactly sixty-six kids. All this in a single day. I looked them up. There's no doubt about it. They're all seals. Breaking. Fast." Bobby said.

"How many are left?" Dean asked. "Who knows? Can't be many. Where the hell are your angel pals?" Bobby asked. "You tell me." Dean said, shrugging. "I'm just wondering." Bobby said, thinking. "What?" Dean asked.

"The apocalypse being nigh and all...is now really the right time to be having this little domestic drama of ours?" Bobby said. "What do you mean?" I asked him. "Well, I don't like this any more than you two do, but Sam can kill demons. He's got a shot at stopping Armageddon." Bobby said. "So what? Sacrifice Sam's life, his soul, for the greater good? Is that what you're saying? Times are bad, so let's use Sam as a nuclear warhead?" Dean asked him, angrily.

"Look, I know you hate me for suggesting it. I hate me for suggesting it. I love that boy like a son. All I'm saying is maybe he's here right now instead of on the battlefield because we love him too much." Bobby said and Dean sighs.

*3rd Person POV*

Dean stands in Bobby's salvage yard and looks around, frustrated, until Castiel appears. "Well, it's about time. I've been screaming myself hoarse out here for about two and a half hours now." Dean said, annoyed. "What do you want?" Castiel asked him. "You can start with what the hell happened in Illinois." Dean said.

"What do you mean?" Castiel asked. "Cut the crap. You were gonna tell me something." Dean growls as he walks up to him. "Well, nothing of import." Castiel said, shrugging. "You got ass-reamed in heaven but it was not of import?" Dean asked him, suspiciously. "Dean, I can't. I'm sorry. Get to the reason you really called me. It's about Sam, right?" Castiel asked.

"Can he do it? Kill Lilith, stop the apocalypse?" Dean asked Castiel. "Possibly, yes. But as you know, he'd have to take certain steps." Castiel said. "Crank up the hell-blood regimen." Dean said and Castiel nods. "Consuming the amount of blood it would take to kill Lilith would change your brother forever. Most likely, he would become the next creature that you would feel compelled to kill. And if you are wondering, since she has similar powers, it would mostly likely happen to (y/n) if she were to consume the blood as well." Castiel explains and Dean sighs.

"There's no reason this would have to come to pass, Dean. We believe it's you, Dean, not your brother nor your girlfriend. The only question for us is whether you're willing to accept it. Stand up and accept your role. You are the one who will stop it." Castiel said and Dean gives him a curious look.

"If I do this, Sammy doesn't have to?" Dean asked him. "If it gives you comfort to see it that way." Castiel said and Dean rolls his eyes. "God, you're a dick these days." He grumbles and he walks a few steps away and sighs.

"Fine, I'm in." he said. "You give yourself over wholly to the service of God and his angels?" Castiel asked. "Yeah, exactly." said Dean. "Say it." Castiel demands. "I give myself over wholly to serve God and you guys." Dean said, firmly. 

"You swear to follow his will and his word as swiftly and obediently as you did your own father's?" Castiel asked. "Yes, I swear." Dean said and Castiel nods a bit. "Now what?" Dean asked him. "Now you wait, and we call on you when it's time." Castiel said.

*(y/n)'s POV*

"Bobby! Dean! (Y/n)! Help! Hey! Hey! Guys! Guys! Help! Dean! (Y/n)!" Sam's voice screams while Bobby and I stare at Dean, shocked at what he just told us. "Correct me if I'm wrong, but you willingly signed up to be the angels' bitch?" Bobby asked Dean, who gives him a look. "I'm sorry. You prefer sucker?" Bobby asked, sarcastically.

"After everything you said about them, now you trust them?" I asked Dean, suspiciously. "Come on, give me a little credit, (y/n). I've never trusted them less. I mean, they come on like shady politicians from planet Vulcan." Dean said.

"Then why in the hell did you—" Bobby started to ask but Dean talks over him. "Because what other option do I have? It's either trust the angels or let Sammy trust a demon?" Dean said and Bobby nods. "I see your point." I said and then we realized that it was strangely quite.

"You hear that?" Dean asked us. "Yeah, that's a little too much nothing." Bobby said and we hurry to the basement and open the window in the door. Sam is on the floor of the panic room, having a seizure.

"What if he's faking?" Dean asked and I turn to him. "You really think he would?" I asked him. "I think he'd do anything." Dean said but then Sam slams against the wall by an invisible force. "That ain't faking." Bobby said and we throw open the door and charge in to get Sam down and pin him to the cot.

"We're gonna have to tie him down for his own safety." Bobby said as he and I hold Sam down. I look over send see Dean standing, looking at his brother in horror. "Dean? You with us?" I asked him but he stands there, frozen. "Dean! Before he has another fit." Bobby said and Dean shakes his head. "Yeah, yeah. Let's just get it over with." He said and he comes over to us and helps us tie Sam down to the bed.

And I start to wonder if what we are doing is the right thing to do. If anything...I think we are making it worse on Sam.

Dean and I were standing in one of the spare bedrooms while Bobby was in the living room, I was pacing around the room. "I'm gonna ask one more time. Are we absolutely sure we're doing the right thing?" I asked Dean. "(Y/n), you saw what was happening to him down there. The demon blood is killing him." He said and I shake my head at this.

"No, it isn't. We are." I said. "What?" Dean asked me, disbelief, and I stop my pacing and stand before him. "I'm sorry. I can't bite my tongue any longer. We're killing him. Keeping him locked up down there. This cold-turkey thing isn't working. If—if he doesn't get what he needs, soon, Sam's not gonna last much longer." I said. "No. I'm not giving him demon blood. I won't do it." Dean said, firmly.

"And if he dies?" I asked him. "Then at least he dies human!" Dean shouts at me and I jump back a bit at this. "Dean, you don't mean that." I said. "I'm sorry, (y/n). It's just...I would die for him in a second, but I won't let him do this to himself. I can't. I guess I found my line. I won't let my brother turn into a monster." He said.

“What if he doesn’t?” I asked. “What?” Dean asked, confused. “What if he doesn’t become a monster? Sure, he’s been acting different lately but it’s still Sam in there.” I said. “He’s got demon blood in him!” Dean exclaimed. “So do I! Did you forget that?! Hell, what if…” I began to say. “Don’t say it!” Dean growled, shaking his head slightly in irritation. “What if I take some demon blood too?” I suggested.

“Shut up, (y/n)!” Dean yelled at me. “No! Listen to me! I can control it.” I yelled back. “Stop.” Dean commanded. “You’ll see nothing happens to me and…” I started to say, but was interrupted by Dean lunging forward and grabbing me by my upper arms.

“I can’t lose you too!” He shouted in my face and I stared back at him, speechless. The rage on Dean’s face loses it’s strength and he now looks broken. “I…I can’t.” He said, his voice breaking. He lowers his head, loosening his grip on my arms. “I’m not strong enough.” He admitted, tearfully. My heart shattered hearing the heartache in his voice and seeing the look of defeat in his eyes. “Dean.” I whispered, my eyes welling up with tears. 

“Please…just stop.” Dean pleaded, keeping his head lowered. I gently slip my arms free from his hands to pull him into a hug. Dean readily returns the hug, squeezing me tight and burying his face into my hair, like he was afraid to let me go. 

"Okay...I'm-I'm sorry...I-I-I just...I just wanted to help." I stammered to him, in a whisper, as we continue to hold each other, I run my hand up and down his back. Then I feel him holding me tighter to him. "You're not gonna lose me. I promise." I whispered as I bury my face into his chest then raised my left hand to his chest and fiddled with the amulet that always hung around his neck.

*3rd Person POV*

After arguing with his hallucinations, the cuffs on Sam's arms and legs snap open then the door opens. Sam sits up, staring; he knows he didn't do this. "Hello?" He calls out but no answer. He gets up and slips out the door.

"Someone here?" He calls out and, again, no answer. Sam hurries quietly out of the basement without noticing Castiel behind the stairs. From a distance, the angel closes and locks the panic room door.

Later, Castiel stands at a railing of the riverfront, looking over the water. The streetlights flicker and he turns to see Anna standing there. "What did you do?" She asked him, a bit of fear in her voice. "You shouldn't have come, Anna." Castiel said, flatly.

"Why would you let out Sam Winchester?" Anna asked him. "Those were my orders." Castiel said. "Orders? Cas, you saw him. He's drinking demon blood. It's so much worse than we thought. Dean was trying to stop him." Anna said. "You really shouldn't have come." Castiel said just as two angels appear on either side of Anna. White light illuminates Castiel; when it is gone, so are the other three angels.

Castiel turns back to the river, staring out at the water. "What did you do, Cas?" A voice demanded and he turns to see Ariel standing near him, her face full of anger. "Ariel." He greets, plainly. "What did you do?" She asked again, emphasizing each word with anger. "Like I told Anna, my orders." Castiel said and Ariel looks at him, concerned.

“You can’t fool me, Castiel.” She said, Castiel tilts his head slightly, in confusion. “I see it on your face, you regret following those orders.” She said, Castiel turns away so she can no longer see his face.

“I am an angel of the Lord.” Castiel said, as if that would change anything. “Do not talk as if you don’t have a mind of your own.” Ariel sneered, crossing her arms. “I serve heaven, I do not serve man.” Castiel growled, turning slightly to glare at her.

“If that was true, you would not have taken Jimmy Novak back as your vessel after he pleaded for you to let his daughter go.” Ariel pointed out, Castiel averts his gaze. “You regret letting Sam Winchester out. Regret breaking Dean Winchester’s trust. Regret turning Anna over.” Ariel listed off and Castiel’s closes his eyes, trying to shut her words out.

“I do not feel any regret. I am simply following my orders.” He said. “And you’re only doing that because you’re scared.” Ariel replied, Castiel goes quite unable to rebut such a statement.

"They really did a number on ya, didn't they?" Ariel said as she looks him as Castiel stands there in silence. "You shouldn't be here." Castiel said and Ariel sighs and shakes her head. "I'm very disappointed in you, Castiel." She said before she disappears, leaving Castiel alone as he starts to feel a twinge of guilt.

Sam begins to work on stealing a car when a gun cocks behind him. "Uh-uh, Sam. The only place you're going is back inside with me." Bobby said, gun aimed at him, as Sam turns to him. "No." Sam said, firmly. "Damn it, boy." Bobby growls.

"You won't shoot me, Bobby." Sam said. "Don't test me." Bobby said, his voice slightly shaking. "You won't do it. You can't do it." said Sam. "We're trying to help you, Sam." Bobby said then Sam takes hold of Bobbh's shotgun so that he can't aim anywhere but point-blank at Sam.

"Then shoot." Sam challenges and there was a long pause before Sam takes the gun and knocks Bobby down, then throws the gun on the ground and returns to hotwiring the car.

Once he does that, he drives off.
